In high-revving engines, the crankshaft spins through engine oil at great speed. As it rotates, it throws oil outward, creating a dense cloud of oil mist around the crank assembly. This phenomenon increases rotating resistance, aerates the oil and reduces the amount of usable oil retained in the sump.

Our precision-engineered crank scraper directly removes excess oil from the crank cheeks on every rotation. The result is improved oil control, reduced drag and enhanced engine stability.

What This Crankshaft Oil Scraper Does

Reduces Rotational Drag
By scraping excess oil from the crankshaft during rotation, the scraper reduces the weight of the crankshaft in wet running conditions. Less oil clinging to the rotating assembly means smoother, freer revving performance.

Improves Oil Retention in the Sump
Instead of being whipped into suspension, more oil remains in the crankcase where it belongs. This ensures a more stable oil supply under acceleration and high RPM use.

Reduces Oil Foaming and Aeration
Excessive oil mist leads to foaming, which can reduce lubrication efficiency. By controlling oil splash, this scraper helps maintain more consistent oil density and lubrication quality.

Helps Prevent Oil Starvation
During hard cornering, braking or high-speed driving, oil starvation can occur when insufficient oil reaches the suction pipe. By keeping more oil properly settled in the sump and reducing aeration, the risk of oil starvation is significantly reduced.

Increases Crankshaft Frame Stiffness
This component also adds structural rigidity to the crankshaft frame assembly. When installed, the rings under the crankshaft frame nuts are omitted, contributing to a more direct and stable mounting setup.

Precision Fitment
We have measured tolerances on used engines with maximum axial play to ensure accurate fitment across engine conditions. The design also allows compatibility with our H-beam connecting rods, making it ideal for performance builds and engine rebuild projects.

Ideal for Performance and Track Use
High RPM and track conditions amplify oil aeration and starvation risks. This upgrade provides additional protection for engines operating under stress.

Engine Rebuild Enhancement
If you are rebuilding a Porsche 944 or 924S engine, installing a crank scraper is a smart preventative upgrade that improves long-term reliability.

Improved Engine Efficiency
Reducing oil drag on the crankshaft can contribute to smoother power delivery and improved engine response.

Long-Term Engine Protection
By minimising oil foaming and maintaining stable oil supply to the pickup pipe, this component supports bearing longevity and overall engine durability.

If you are building, restoring or upgrading a Porsche 924S or 944 engine, this crankshaft oil scraper is a proven solution to improve oil control, reduce drag and enhance engine stability under demanding conditions.
